ALBERT S. NEWTON, OF PROVIDENCE, RI'IODE ISLAND.

SHOWER-HEAD.

Specification of Letters Patent.

Patented July 28, 11914.

Application filed April 8, 1914. Serial No. 830,349.

T 0 all whom it may concern:

Be it known that I, ALBERT S. NEWTON, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Shower-Heads, of which the following is a specification.

My invention relates to shower heads particularly adapted for use as a part of a bathing system, and to similar apparatus.

The principal objects of my invention are accessibility to the interior for cleansing purposes; to provide such a device for scraping the inner face of the perforated plate as will not interfere with the passage of water through any of the perforations; to insure a firm and uniform contact of the scraper throughout its length with the perforated plate; to provide means for indicating from the exterior of the head the location of the scraper within the head; to provide an operating handle; and to attain these ends in a strong, simple and inexpensive structure.

My invention consists therefore 1n the means and mechanism for producing the results above specified substantially as hereinafter described and claimed, and as shown in the accompanying drawings which form a part of this specification herein.

Figure 1 is a side view of my shower head, Fig. 2 a lan view of the same showing a portion of the body broken away, Fig. 3 a section of the same partially in side elevation, taken on line as, w, of Fig. 2, Fig. 4 an enlarged section of the arm operating mechanism taken on line a a, of Fig. 2, and Fig. 5 a section of the arm operating mechanism taken at an angle of ninety degrees from the plane of the section shown in Fig. 4.

Like reference characters indicate like parts throughout the views.

My invention in its preferred form of embodiment comprises a head having a conical body A provided with a neck B having attaching threads 6. A downwardly directed rim or flange C upon the margin of the body has external threads 0, adapted to engage internal threads (1 upon a ring D provided with an annular supporting shoulder (Z Depending projections F upon the ring D are for convenience in screwing the ring upon the flange. Upon the shoulder (Z is a plate G having radially disposed rows of perforations g for the passage of water.

G is a washer located between the plate G and the flange C. The ring permits the removal of the plate Gr but it will be understood that if desired the plate G may be integral with the body A. The accumulations of foreign clogging matter carried by water tend to collect at the margins of the openings 9 upon the back of the plate G. This matter is removed by means of a scraper or arm now to be described together wlth its operating mechanism.

The plate G has a central opening it in which is journaled a pin H attached to or integral with whose outer end is a head I. This head in the present instance consists of a nut z fixed to external threads t upon the pin by means of interengaging threads 6 upon the nut. The head I is provided with a diametrical opening j in which is frictionally held a pointer arm J which traverses the head and extends at both sides thereof. One end of the arm J has an inwardly direc-ted indicator point j adjacent or in contact with the plate G. The upper portion of the pin H as at K is of increased diameter, affording a bearing shoulder 70 upon the upper surface of the plate G. Near its extreme upper end the pin H has a portion L of slightly reduced diameter which is provided with external threads Z, and the portion L is provided with a vertically disposed diametrical slot m extending downwardly into a portion of the part K of the pin. A nut N has internal threads n engaging the threads Z. Mounted in the post or pin H is a broad arm or scraper O disposed with its lower edge in contact with the plate Gr throughout its length. In detail the arm 0 has in its lower margin a rectangularly cutaway recess P, and above this recess a somewhat longer and more shallow rectangular marginal recess Q. The arm is located in the slot m of the post, so that the portion of the post below the slot is loose in the recess P. A slightly curved bar R of preferably re silient material has a concave face r upon its under side, and the ends of the bar rest in the recess Q, and in contact with the upper edge of the arm 0. As this bar passes through the slot at the turning of the nut M upon its upper edge forces the arm 0 clownwardly and insures an intimate contact of the lower edge of the arm with the surface of the plate G. This is possible, since the depth of the slot P is greater than the distance of the bottom of the slot m above the plate G. Thus the arm is insured of such a as to insure the effective performance of its functions.

It is desirable that the arm should normally be in such a position when at rest as not to cover any of the perforations of the plate 9. This end is assisted by means of the member J which is parallel with the arm 0. The operator is enabled to note the direction of the exposed pointer with relation to the series of perforations and can rotate the pin H accordingly. The pin J afiords also a convenient means for manually I with a series of perforations, and with a centurning the post or pin.

What I claim is,-- V

1. In a shower head, the combination with a body, of a plate upon the body provided with a series of perforations, and with a central opening, a pin rotatably mounted in the opemng provided upon its inner end with a longitudinally disposed transverse slot, and

with external threads, an arm passing through the slot and in contact with the surface of the plate, a spring member in the slot engaging the arm, and a nut upon the spring member provided with threads en- 1 gaging the first mentioned threads.

2. In a shower head, the combination with a body, of a plate upon the body provided with a series of perforations, and with a central opening, a pin rotatably mounted in the opening provided upon its inner end with a longitudinally disposed transverse slot, and with external threads, an arm passing through the slot and provided with a recess in its lower margin to loosely receive a portion of the pin and of greater depth than the height of the unslotted portion of the pin above the plate, a spring member in the slot resting upon the arm, and a nut pro vided with threads engagin the firstmentioned threads above the spring member.

3. In a shower head, the combination with a body, of a plate upon the body provided tral opening, a pin rotatably mounted in the opening provided upon its inner end with a longitudinally disposed transverse slot, and with external threads, an arm traversing the slot and provided with a recess in its lower margin to loosely receive a portion of the pin, and provided with a recess in its upper margin, a curved spring member traversing the slot and resting in the last mentioned recess, and a nut upon the threads engaging Copiesof this patent may be obtained for five cents each, by addressing the GOmmissioner of Patents, Washington, D. 0.
